added links to PWM Oscillator by steven: https://forum.renoise.com/t/pwm-with-a-single-sine-wave-sample/32283
and the ‘more tuned devices’ by dblue: https://forum.renoise.com/t/2-7-more-tuned-devices/32280
also, for those tips/tricks that the poster provided an xrns-file for, i downloaded that file and uploaded it on my own server just in case a download-link in a forum thread breaks. furthermore, i credited most of the tips to the original poster, with a link to the user-page on the forum, as well as a link to the forum-thread in the cases where that was not present yet.
hope people still find this useful. i recently figured out it functions pretty well as a link to various cool tricks posted in the forums, for when you are having trouble finding a certain something.
if anyone has a problem with me hosting their xrns on my own server, let me know and i’ll take it down. (i think so far all the files are by dblue though, so i hope he’s okay with it 
)
